Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"core using one algorithm" » "core using our algorithm", "core using _ algorithm", "core using mom algorithm", "code using one algorithm", "care nursing one algorithm", "core using open algorithm", "core using pre algorithm", "core using online algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("core using one algorithm") or ("modified multiobjective optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("core using one algorithm") OR ("modified multiobjective optimization algorithms")).
• Removing quotes may allow a broader search: (( core using one algorithm ) or ( modified multiobjective optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("core using one algorithm") or ("modified multiobjective optimization algorithms"))*.
